Experts advise early preparation for extended fall allergy season amid climate changes

As allergy season arrives earlier and lasts longer due to shifting climate patterns, experts are encouraging Americans to take proactive steps in managing fall allergies. According to the United States Environmental Protection Agency, the frost-free season has lengthened by more than two weeks on average across the country. This extended period of warm weather means plants start blooming sooner, remain active for a longer time, and produce increased amounts of pollen.

“The prolonged warm weather means plants bloom earlier, stay around longer and make more pollen — causing sneezing, coughing, itching, watery eyes and runny nose, as well as triggering asthma attacks and hay fever,” said allergist James Tracy, DO, president of the American College of Allergy, Asthma & Immunology (ACAAI).

Ragweed is one plant that thrives in warmer conditions and is recognized as a common environmental allergen by the EPA. Traditionally blooming from late summer into early fall and ending after the first frost, ragweed’s growing season now extends further each year due to later frosts.

While individuals cannot control the weather or pollen production outdoors, several strategies can help manage symptoms. The ACAAI offers five recommendations: avoid exposure during high pollen counts; change clothes immediately after being outside; begin taking allergy medications about two weeks before symptoms typically start; consider immunotherapy for long-term relief; and consult with a board-certified allergist if symptoms worsen or new ones develop.

James Tracy advised monitoring daily pollen reports and limiting outdoor activities when levels are high. He also recommended wearing hats and sunglasses to protect against airborne allergens and using NIOSH-rated masks when mowing lawns or performing other outdoor tasks.

Starting medication early is emphasized so that people do not wait until symptoms appear. Continuing treatment for at least two weeks after the first hard frost is suggested because nasal and eye allergy symptoms may persist even after airborne pollen decreases.

For those with persistent or severe allergies or asthma triggered by seasonal allergens like ragweed, immunotherapy—administered via shots or tablets—may provide significant long-term benefit by desensitizing patients’ immune systems over time.

The ACAAI stresses that seeing an allergist can help individuals receive tailored care plans. Board-certified allergists are equipped to diagnose both allergies and asthma accurately and can offer treatment options including immunotherapy.

“Ask your allergist about getting tested for asthma if you’re coughing or wheezing more often than before,” added Tracy.

Founded in Arlington Heights, Illinois, ACAAI represents over 6,000 medical professionals specializing in allergy care. The organization promotes collaboration among its members toward improved patient outcomes through research and education initiatives.
